This invention has to do with shingles, more particularly, shinglescomposed of materials generally employed in the manufacture of so-calledprepared rolled roofing, which is made up of a felt-like base saturatedwith bituminous materials, surfaced with bituminous materials of highermelting point into which are embedded granulated mineral particles.

It is one of the objectsvof this invention vto provide an improvedinterlocking shingle comprising a plurality of units that will readilyinterlock in a manner differing from anything heretofore used in theart, and one which will greatly expedite the laying of roofs andcoverings for side walls.

provide an improved roofing material in which the interlocking means areso formed that when the units are being laid on a roof or side wall theengagement of one unit with another takes place in a downward direction;the units being maintained in position by their own weight prior tobeing nailed down. Heretofore the interlocking engagement of one unitwith another was effected from below in an upward direction makingt-necessary to manually hold' the units in place until secured withnails. .A more specific object of this invention, however, is to providea hook like'means at one corner, one which does not protrude materiallybeyond the general bor'- der outline of the shingle, and a receivingmeans also within the outline o1 the shingle unit, the

hook-like portions being formed by cuts andthe receiving means alsoformed by cuts.

The further object of this invention is to provide an improved shinglethat when laid in the same course, the interlocking means will c'o-actat the side lapped portions when the shingles are brought together, tocause the edges thereof to 40 be secured and for the purpose ofpreventing the wind from turning up the edges thereof.

A further object is to provide shingles of such shape that they willpresent a. design of conventional configuration, and at the same time to4 eliminate the frillsof various attachments that are sometimes employedto sec'ure the edges of shingles.

Still further, and a most important feature of this invention is toprovide a locking means that will be diflicult to pull loose, or breakoil', during the application of the shingles, and to provide.

a nailing range without weakening the securing featres of the lockingdevice.

.With the above and other objects in view, the

5 improved shingles consist of their whole, or their It is thefurtherqbject of this invention to,

(Cl. 10S-7)' parts, and combinations as set forth, and all equivalentsthereof.

It is to be understood that vnails may be provided to secure theseshingles at any desired location that would be covered by an associated5 shingle.

The annexed drawing and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various me- 10 chanical forms inwhich` the principle of the invention may be used.

In the accompanying drawing, the same ref-v erence characters designatethe same parts in all of the views.

Fig. l is a plan view of a blank, forming my preferred shingle; Fig. 2shows a plan view of a modification, being one type of reversibleshingle embodying the same general characteristics of Fig. l Fig. 3shows another plan view of another '20 shingle unit embodying thefeatures of reversibility and the same general interlockingcharacteristics; Fig. 4 is la plan view of a section of a roof coveredwith the shingles of Fig. 1; Fig. 5 is a plan view of a modified formshowing a dif- 25 ferent angled outline; Fig. 6 is a section throughline 6`6 of Figure 4.

Referring now to the drawing, the numerals designates the exposedportion, and each' shingle as cut consists of an exposed portion of ageneral 30 symmetrical outline.

In Fig. 1, the numeral 9 designates the downwardly `protruding hook-likelug which is formed by the inwardly extending slot or slit 2|. The cutforming the opening which cooperates with 35 the lug 9 is designated bythe numeral I0. The

. exposed edge II is indicated as extending at right angles to alongitudinal edge I2 which is the bottom exposed edge, and the coveredlapped portion I3 when assembled on the roof or side 40 wall is shown inFig. 4.

In Fig. 2, numerals I4 and I4 designate what may be either the exposedlower edge or the upper covered edge. Lug 9 and cut I0 are adapty ed toco-act .with similar shingles when assem- 45 bled on the roof witheither edge I4 or I4 being exposed to the weather, depending uponwhether the shingles are being laid from left to right, ory from rightto left.

In Fig. 3, a re-arrangement of locking lugs 9 50 and 9', and receivingmeans, or openings 20 and 20', is illustrated, and this shingle has thesame reversible characteristics as that of Fig. 2, except that it isadapted to be laid in one sidewise direction.

Fig 4 is a section of a roof, while showing only the shingle illustratedin Fig. 1, designates the method of adapting all the Figs. 1 to 5 to theroof or side wall surface, the same numerals in each figure designatingthe function of the portions shown in Fig. 4.

In none of the known prior art is there shown a shingle having a lockingcorner means within the general border outline of the shingle, andhaving the same adapted to co-act for locking registration in such anovel and practical manner as disclosed in this invention. Further, inno instance is there disclosed in the prior art a shingle that is sowell adapted for locking engagement as by hooking-in, in the directionthat the succeeding shingles are applied. This manner of lockingengagement has been found to be extremely advantageous to the roofer,because the lug 9 is generally less damaged in shipment, andy Awhenhandled by the roofer, therefore, is less apt to break off because itdoes not protrude bey yond the lower or side edges, as shown in theprior art, particularly as in such patents as those to Theilacker No.1,710,954; Harshberger No. 1,718,933; Theilacker-No. 1,725,551; FinleyNo. 1,604,745 or Harshberger No. 1,657,082.

Referring now to the modification shown in;

Fig. 5, it will be noted that the diagonally disposed side edge |5 andthe bottom or weather edge I2, are at acute angles, and while this is.not my preferred form there are some advan-`V tageous features in thistype by reason of a better side edge angle which affords betterprotection from angularly driven snow and rain.

Other modes of applying the principle of my invention may be employedinstead of the 'one explained, change being made as regards themechanism herein disclosed, provided the means stated by any of thefollowing claims or the equivalent of such stated means be employed.

lI therefore particularly point out and distinctly claim as myinvention:-

1. A shingle having a receiving means wholly surrounded by the materialof the shingle, and a locking lug inoblique relation to an.axis of theshingle and to the longitudinal axis of said receiving means, saidshingle adapted to be aS- sembled with the locking lug entered throughthe said receiving means of an adjacent shingle and one edge of saidlocking lug providing a stop for disengagement of the interlocking partswhen movement of said locking lug is attempted in a direction normal tosaid axes.

2. A shingle having a locking lug along an edge thereof and in obliquerelation to said edge, and receiving means Wholly surrounded bythematerial of the shingle and adapted to receive the locking lug of asimilar shingle in assembly to create an interlock substantiallyinseparable to said shingle edge.

3; A shingle having a receiving means adjageneral direction of saidshingle edge, and a locking lug on said shingle obliquely disposed tosaid axis, said shingle adapted to be assembled with other similarshingles with their receiving means axes substantially parallel and withthe locking lug of one shingle entered through the receiving means of anadjoining shingle to create an interllock substantially inseparable tomovement of the shingles normal or parallel to said axis of thereceiving means. A

5. A shingley having a slot in one edge obliquely ndisposed theretodetermining the lock edge of a locking lug, and receiving means whollysurrounded by... the material of the shingle spaced therefrom andadapted to receive the locking lugl of anotherl in assembly to create asubstantially inseparable interlock to-movement normal or parallel tosaid shingle edge.

6. A shingle having slots in opposite edges, said slots determininglocking lugs each obliquely disposed to its respective edge, and saidshingle having lug-receiving means wholly surrounded by the material ofthe shingle adapted to receive a locking lug of asimilar shingle inlocking engagement to create an interlock substantially inseparable tomovement of the shingles normal to said locking lug edge.

7. An assembly' of shingles, each having a locking lug at a lowercorner, and lug receiving means wholly 'surrounded by the material ofthe shingle in 4an adjacent corner and adapted to receive a locking lug'of an adjoining shingle, said shingles assembled with similar shinglesin a longitudinal course with the lower edges of the shinglessubstantially parallel and interlocked; said locking lugs enteredthrough the receiving means of adioining shingles and positioned beneaththe material surrounding said receiving means.

8. An assembly of shingles each having at a lower weather corner alocking lug determined by an edge slot and another edge of the shingle,

and in an adjacent weather corner a lug receiving means whollysurrounded by the material of the shingle and adapted to receive the lugof an adjoining shingle, said shingles assembled in a longitudinallyextending course with adjacent shingles in lapped relation and with thelocking lug in the lower weather corner of one shingle entered throughthe receiving means of an adjoining shingle and positioned beneath thematerial surrounding said receiving means.
